This invention relates to tools for use in mounting or dismounting tires on onepiece rims which have a removable bead engaging flange and a removable locking pf ring engaging-the rim outwardly of said flange to prevent displacement of the same. Such rims are particularly used'in connectionwith large heavy duty tires which are so bulky an relatively nonyielding as to offer considerable resistance to the placing of the removable flange and the locking nn 'l he rincipal object of my invention is to provide a tool adapted to be used with rims of this character by means of which the removable flange may be easily pressed into place against the resistance offered by the tire, and the locking ring at the same time caused to snap into place. The tool is also 80 provided with an attachment rendering the same available for further depressing the flange to enable the locking rin to easily removed when desired to withdraw the flange and remove the tire. N A further object of the invention is to produce a simple and inexpensive device and ygt one which will be exceedin 1y effective r the purpose for which it is esigned. These ob ects I accomplish by means of 80 such structure and relative-arrangement of parts as will fully appear by a perusal of the following specification and claim.

In the drawings similar characters of refg erence indicate corresponding'parts in the 86 several views:

Fig. 1 is a side elevation of my improved tool asinuse in connection with a rim showha'ndle-bar of suitable length, which at one end is pivoted to a combination handle and W rim engaging member intermediate the ands minating in a tapered of the same. Said member comprises a bandle portion 2 above the. lever and a lower mm, earn-cams. Assmrton me some; new ooiirounon,

arm 3 terminating at its end in a hook 4 turned toward the lever. De ending from and rigid with the lever'near t e connection of the same with the arm 3 is a stem 5 terpoint 6. The. rim with which the tool is to be used comprises a main rim portion :7 having a bea engaging flange 8 seated adjacent one edge of the same, and a removable bead en- 10, a a ted to partially receive the usual gaging flange 9 adapted to be slid onto the slit lockmg ring 11, which when in place 00- v operates with the fla'jlge 9 to prevent. removal of the same. When mountin a tire 12 onto the rim its be beads are first slldonto the, rim as usual.

The flange 9 is then placed on the rim If resistance of the tire however preventsthe flange from thus moving into lace and is so great that it is almost imposslble to press the flange down by hand the necessary distance and at the same time force the spring locking ring into seating position inits roove. v

With my improved tool however such'difficulties are entirely overcome. In

the tool the tire and rim are laid flat on the floor with the locking ring edge up ermost. The tool is positioned so that the ever extends across the tire with the arm 8 depending alongside the rim with its book 4 engagivreg the lower edge ofthe rim as shown.

1th one hand grasping the handle 2 and i the other the lever the stem 5 ismanipulated so that its point engages the removable flange; the locking ring being first placed asxnear-in s'ition as it is possible to (16,. as'indicate in Fig. 1. Depression of the lever then causes the flange -9 to be depressed, :as will be evidentyand when it is about in its proper position the handle 2 is manipulated, while the pressure on the lever is maintained, so that the side of the stem presses against the locking ring and forces the same into seating positlon in the groove,

as shown in Fig. 2.v When thus acting a ainst the locking ring, the pointed en 0% the stem moves "across the depressed surface of the flange from the position shown in Fig. 1 to that shown in Fig. 2. It is of course to be understood that the free end of the ring is first inserted and then the tool is shifted about the rim to take another grip and these operations are repeated until the locking ring is seated over its full length.

To enable the tool to be used'when it is desired to remove the flange I provide a sleeve or socket 13 ada ted to fit over the oint of the stem 5 an having, a shallow -shaped notch 14 cut in its outer end so as to en age the outer edge of the removable rim ange, as shown in Fig. 3. This sleeve is removably held in proper position on the stem by a pin 15 inserted transversely through said sleeve and the stem. .The notch in the sleeve prevents the same from slipping off the flange and spaces the stem and sleeve from the rim proper the necessary distance to enable the locking .ring to be withdrawn into the space between the sleeve 80 and the position normally occupied by said ring when the lever is further depressed from the position shown in Fig. 3.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in de-' tail the present and preferred construction of the device, still in practice such deviations 40 from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.-

Having thusdescribed my invention what I claim as new and useful and desire to secure by Letters Patent is:

A rim-tool comprising a rigid arm having a handle-extension pro ecting from one end thereof and i 'd therewith, a hook element on one end 0 the armto engage one side of the rim and facing the other end of the arm, a rigid lever pivoted at one end on the arm at a distance on the latter from the hool: greater than thewidth of a rim and. promoting from the hook side of the arm and an e ement to enga ethe other side of the rim rigid with and epending from the levler toward the 'l-liiook.f I fix n testimony w ereo .a m si ature.
